<p><em>February 1, 2018</em></p>
<p>Django 2.0.2 fixes a security issue and several bugs in 2.0.1.</p>
<div class="section" id="s-cve-2018-6188-information-leakage-in-authenticationform">
<span id="cve-2018-6188-information-leakage-in-authenticationform"></span><h2>CVE-2018-6188: Information leakage in <code class="docutils literal notranslate"><span class="pre">AuthenticationForm</span></code><a class="headerlink" href="#cve-2018-6188-information-leakage-in-authenticationform" title="永久链接至标题">¶</a></h2>
<p>A regression in Django 1.11.8 made
<a class="reference internal" href="../topics/auth/default.html#django.contrib.auth.forms.AuthenticationForm" title="django.contrib.auth.forms.AuthenticationForm"><code class="xref py py-class docutils literal notranslate"><span class="pre">AuthenticationForm</span></code></a> run its
<code class="docutils literal notranslate"><span class="pre">confirm_login_allowed()</span></code> method even if an incorrect password is entered.
This can leak information about a user, depending on what messages
<code class="docutils literal notranslate"><span class="pre">confirm_login_allowed()</span></code> raises. If <code class="docutils literal notranslate"><span class="pre">confirm_login_allowed()</span></code> isn't
overridden, an attacker enter an arbitrary username and see if that user has
been set to <code class="docutils literal notranslate"><span class="pre">is_active=False</span></code>. If <code class="docutils literal notranslate"><span class="pre">confirm_login_allowed()</span></code> is overridden,
more sensitive details could be leaked.</p>
<p>This issue is fixed with the caveat that <code class="docutils literal notranslate"><span class="pre">AuthenticationForm</span></code> can no longer
raise the &quot;This account is inactive.&quot; error if the authentication backend
rejects inactive users (the default authentication backend, <code class="docutils literal notranslate"><span class="pre">ModelBackend</span></code>,
has done that since Django 1.10). This issue will be revisited for Django 2.1
as a fix to address the caveat will likely be too invasive for inclusion in
older versions.</p>
